When my h was in his crisis, he was so self absorbed that the neighborhood bully down the street shoved our daughter onto the pavement and kicked her, and he did nothing about it. When I went down the street to talk with the parents, my H was back at home on the computer emailing OW and looking up information on "Aries and Taurus" love horoscopes.
There were a handful of times where he was so checked out. I had to become the primary parent taking care of things. Once our D got sick, very sick, and I had to arrange to take her to the doctor, getting a ride with our neighbors to town. What was he doing when this went on? At home, on the computer again doing searches on porn. he gave me some excuse to stay home that day.
It's really really hard to stand back and watch them be so detached like this.
